Anurse administers an intravenous solution of 0.45% sodium chloride. in what category of fluids does this solution belong?

Answer is: hypotonic.

Tonicity is the relative concentration of solute (in this example sodium chloride NaCl) dissolved in solution which determine the direction of diffusion.

A hypotonic solution has a lower concentration of solutes (sodium chloride) than another solution.

Normal saline is 9 grams NaCl dissolved in one liter of water.

In this example is 4.5 grams of NaCl dissolved in one liter of water.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
